[PATCH v6 2/6] clang-format: avoid spacing around bitfield colon

[Karthik Nayak <karthik.188@gmail.com>]

The spacing around colons is currently not standardized and as such we
have the following practices in our code base:
- Spacing around the colon `int bf : 1`: 146 instances
- No spacing around the colon `int bf:1`: 148 instances
- Spacing before the colon `int bf :1`: 6 instances
- Spacing after the colon `int bf: 1`: 12 instances

Let's formalize this by picking the most followed pattern and add the
corresponding style to '.clang-format'.
